Ceeniu Smart Car Air Freshener CF3 (Mint Ice, Blue)

How long does the battery last between charges?

The built-in rechargeable battery typically lasts 2-3 weeks with regular daily driving. Battery life depends on usage frequency and scent intensity settings. The auto on/off feature helps conserve power by only operating when the vehicle is running. A full charge via USB-C takes approximately 2-3 hours.

Can I adjust the fragrance intensity?

Yes, the CF3 offers multiple intensity modes. Press and hold the power button for a few seconds to cycle through different strength levels. Mode 1 provides subtle fragrance suitable for sensitive noses, whilst Mode 2 delivers stronger scent coverage. The LED light indicates which intensity level is active.

What scent refills are available and how do I replace them?

Ceeniu offers four scent options: Mint Ice, Roman Holidays, Velvet Vanilla and Mimosa. Each 135ml refill bottle lasts approximately 160 days. To replace, simply unscrew the empty bottle and attach the new one. The CF3 uses proprietary refills designed specifically for this model's ultrasonic technology.

Will this work in any vehicle type?

The CF3 fits standard cup holders measuring 6-8cm diameter and works in cars, vans, trucks and motorhomes. The vibration sensor adapts to different engine types and driving conditions. The cordless design eliminates power outlet requirements, making it suitable for vehicles without 12V sockets in convenient locations.

Is the fragrance safe for people with allergies or sensitivities?

The 100% natural, alcohol-free formula is specifically designed for sensitive individuals. French-sourced ingredients contain no harsh chemicals or synthetic additives. However, people with severe fragrance allergies should test tolerance gradually. The adjustable intensity allows you to start with the lowest setting.

How does the auto on/off feature work exactly?

The built-in vibration sensor detects engine movement and road vibrations to automatically activate the diffuser. When you start your engine, the sensor triggers operation within seconds. When parked with the engine off, it automatically shuts down after detecting no movement for several minutes, conserving battery and fragrance.

Can I use this diffuser outside of my car?

Yes, the CF3 works anywhere you need fragrance - offices, caravans, tents, or boats. The motion sensor will activate when the device detects movement or vibration. For stationary use, you can manually activate it using the power button. The quiet operation below 35dB makes it suitable for indoor environments.

What maintenance does this diffuser require?

The CF3 requires minimal maintenance due to its waterless design. Occasionally wipe the exterior with a damp cloth to remove dust. The ultrasonic chamber is self-cleaning and doesn't accumulate residue. Simply replace the fragrance bottle when empty and charge the battery as needed. No filters or internal components require regular cleaning.
